Error using image Error using image TrueColor - How to plot images created by joining arrays instead of using imread

Hello there, i have a question.

Let's suppose i have a image of 3x3 pixels with only a blue dot on the center.

>> image=imread('dot.bmp')

image(:,:,1) =

255  255  255
255    0  255
255  255  255

image(:,:,2) =

255  255  255
255  162  255
255  255  255

image(:,:,3) =

255  255  255
255  232  255
255  255  255

If i get the arrays separately and join them into an array:

dot(:,:,1) = [255 255 255; 255 0 255; 255 255 255] dot(:,:,2) = [255 255 255; 255 162 255; 255 255 255] dot(:,:,3) = [ 255 255 255; 255 232 255; 255 255 255]

>> image(dot) Error using image Error using image TrueColor CData contains element out of range 0.0 <= value <= 1.0

The question is, what should i do to make it work?

Regards.

image( uint8( dot ) )

should work, although just doing what you put works for me too in R2016b
